Determination of quality of life of patients with morbid obesity with simultaneous analysis of three questionnaires - SF-36, GIQLI and QUALITY OF LIFE INDEX QUESTIONNAIRE

Nowadays a great number of different questionnaires and forms for to assessment of quality of life (QL) of patients, including patients with morbid obesity, have been developed and used. To estimate the QL, we used three questionnaires: SF-36, GIQLI and the original one assessing the quality of life index (QLI), developed by us specifically for patients with morbid obesity. The main group consisted of 26 patients with morbid obesity, the av. age of which was 36,7 ± 0,3 years, the av. weight - 125,1 ± 24,5 kg (from 93 to 160 kg) and the av. BMI - 42,8 ± 8,1 kg/m 2. The control group consisted of 26 healthy persons without any comorbidities and morbid obesity. All indicators in all groups are higher than in healthy persons (the difference is statistically significant (р £ 0,05). From these data it follows that, as in the case of SF-36 questionnaire, there are significant differences between the two groups in all blocks of questions indicating a lower level of QL in patients with morbid obesity compared with healthy. Similar results were obtained in the analysis of QLI. Analysis of the three questionnaires revealed that all demonstrated a significant difference between the QL in patients with morbid obesity from that of healthy persons. These figures differ both in total points and in individual clusters of questions. A study of the correlation between BMI and levels of QL showed that, according to the GIQLI questionnaire has not represented. According to the questionnaire SF-36 there is inverse dependence between indicators of physical well-being and body weight of the patient. The same relationship exists in the QLI questionnaire in the block of disease-specific questions.
